Spectra S1 vs S2 Comparison: Which Breast Pump is Right for You?

spectra s1 vs s2

When it comes to their baby’s needs, mothers want to provide the best care possible. So, it’s no surprise mothers want to do their due diligence to determine the best breast pump for them. This article will evaluate breast pumps from Spectra Baby USA. In this full review, we’ll be doing a “Spectra S1 vs S2 Comparison” to see which is the better choice.

Spectra S1 vs S2: What Do They Have in Common?

The Spectra S1 vs Spectra S2 breast pumps perform the same functions and, as such, are similar in most ways except for three or four differences which we will touch on next.

Closed Pump

Both the Spectras have a closed pump system. The closed pump is connected for back-flow protection to hinder the milk from entering into the pump’s motor from the tubing. As a result, there is less possibility for contamination. In other words, it is unlikely that bacteria will grow in the pump because there is no contact from the milk to the machine.

Pump Settings

Another critical feature that both the S1 and S2 have is the pump settings. Being able to control the settings means that you can control and adjust the milk’s speed flow. Managing the speed is essential because the milk sometimes flows faster than other times, depending on the stage and the session. Both types have twelve different levels of suction as options.

Motors

The S1 and S2 both have motors that can go up to 250 mmHg. This section rate is pretty quick, which helps you get the job done quickly. The S1 and S2 are both quiet, so if you go off to pump, you will be able to do that with complete privacy as it will not make sounds to draw attention to what you’re doing or cause your baby to awaken from the noise.

Accessories

When it comes to accessories, both pumps have bottles, valves, and flanges. You can buy additional accessories if desired, such as a breast pump bag to hold your pump parts at an additional cost.

Double Pumps

A feature that moms love is that Spectras can turn into double pumps, which pump both breasts simultaneously. The double-pump is a tremendously time-saving factor.

Extra Features

Both versions of the Spectra breast pump feature an LED digital display, which is always a plus. They also have a night light for a nighttime pumping mommy.

Spectra S1 vs S2: What Are Their Differences?

The primary difference between the two breast pumps is the rechargeable battery found in the S1, which increases the price. The S2 does not come with a built-in rechargeable battery and is, therefore, less costly.

By having a rechargeable battery, you’re able to pump anywhere whenever you need to. The only requirement is that you charge the battery with an AC adapter. At full charge, you can get three hours of pumping.

Another difference is the weight of the two pumps. They weigh about the same three pounds; however, the S2 is just slightly under three pounds.

A minor difference in the pumps is the color; the S1 is blue and white while the S2 is pink and white.

Spectra S2: Pros & Cons


Spectra S2 Plus Electric Breast Pump

Pro

  • The price is more affordable for the S2 breast pump.
  • You can pump both breasts simultaneously.
  • Compared to most similar-quality medical grade pumps, it’s much more lightweight and portable.

Con

  • Some moms feel the absence of a built-in battery is a disadvantage when away from an electrical outlet.
  • The impression is that the pump’s intensity may go down when used as a double breast pump instead of a single.

What are Moms Saying About Spectra 1

One mother shared, “The S1 is hands down the best I’ve tried. I prefer a suction strength that allows me four to eight ounces per session. Owning my own business is quite stressful, especially today, where I’m juggling numerous responsibilities; I can keep up with my day with this pump.” 

Another mom also praised Spectra 1 by saying, “The S1 is great because it can pump the same amount as other breast pumps, but it does it in half the time. I can also charge the battery anywhere, so I don’t have to worry about where to plug it, which is a tremendous relief.”

What are Moms Saying About Spectra 2

One fellow mom finds Spectra 2 life-changing. She says, “The S2 pump has completely transformed my life. Not only is this pump significantly more powerful, but it is also more comfortable and straightforward to use. Now I can pump enough to always have enough breast milk in the refrigerator.

Another mother finds convenience in her Spectra 2 by saying, “I make time by pumping while driving. I bought a little adapter for the car that lets me plug in the S2; I wear my pumping bra and cover myself up. Although it seems odd, it’s saved me a lot of time.

Spectra vs Medela Pump: How Do the Pumps Compare?

The Spectra and the Medela pumps perform the same basic functions. The difference between these two is the adjustability of the suction and vacuum settings. You can only control the Medela pump by one dial, whereas the dials are separate on the Spectra, which offers more control over the sessions. 

New moms prefer the Spectra as their first choice for breast pumps because it’s more comfortable than the Medela. These minor differences give the Spectra an advantage.

Who Should Get the Spectra S1?

For active moms, the Spectra S1 is not only portable and quickly rechargeable but also quiet and inconspicuous for a gentle pumping experience. The Spectra S1 plus can be used as a single or double pump, saving a lot of time.

Who Should Get the Spectra S2?

If you’re a first-time mom with a low milk supply, then the Spectra S2 pump is ideal for you. Moms believe it is gentler on women with no experience with pumping. It’s lightweight at less than three pounds, and it’s portable and has different cycle setting options. Additionally, the Spectra S2 plus is a double electric breast pump.
